I've picked up 2 of these. The first on clearance for $49.99 which I currently have built and displayed and the second one I got earlier this summer for $20 which is still MISB. Very good set that is definitely worth it.

I got the last one the local Discovery Store had when they discounted them half off, so I got it for about $50, which wasn't too bad, especially considering the fact that I used a GC my company gave me to buy it

I just purchased one off Ebay Brand new Shipped for $54.00+Bonus Lego Final Duel I & II. I can't wait to get it,and have fun putting it together. I never really saw these that often at retail around here. If I did see them somewhere,they wouldn't last too long,and at the time were a little to pricey for me.
